chef install should warn users if local cookbook isn't used

[mhedgpeth]

Description

If you have this Policyfile.rb in a cookbook:

name 'kitchen-cloudpassage'

default_source :supermarket, 'https://supermarket.chef.io'

run_list 'recipe[chef-vault::default]', 'recipe[mycookbook::default]'

But forget to add this line:

cookbook 'mycookbook', path: '.'

Then a chef install Policyfile.rb command will dutifully look to your supermarket for the mycookbook cookbook. This could get very confusing.

Suggestion: warn the user that they are NOT using the local cookbook (as defined in the metadata.rb that is located as a peer to the Policyfile.rb file.
